Detail description.

Amman-t key ba n-/1:.The, machine has a plurality of banksof amounts keys for controlling differentials for adding the amounts into the selected tot-alizers. Depression of an amount key cams a detent 31 (Fig.

' 5) downwardly until afiattened stud 32 thereon engages above a shoulder 33 on the key, thereby holdingthe-key in depressed posit on.

'The detent 31 is held in its home position by means of a spring 34 stretched between the 'ing shown) secured to a release shaft 42, en-

*gages the tail 39 near the end of the operation of the machine to move the detent 31 downwardly to disengage the flattened stud 32 from the shoulder 33, thereby'releasing the depressed amount keys 30. The means for rocking the releaseshaft 42 will be hereinafter described. I Transactzon ban7c.The machine may be provided with one bank or a plurality of transaction keys (Fig. 6) which are adapted to control the selection of totalizers such as is illustrated and described in the above mentioned Shipley application. Each bank is provided with a detent 51 which cooperates with studs 52 on the transaction keys m hold the transaction keys in their depressed position. Each detent 51 is movably supported on arms 53 and 54; The arm 54 is provided with a tail 5 5 with which an arm 56 on the release shaft 42 cooperates to release the transact-ion key near the end of the operation of the machine in a manner to be later described.

lllachz'ne release me0ham'sm;The machine release mechanism is well known and is fully illustrated and described in the previously mentioned Shipley application'and in Letters Patent of the United States No. 1,602,596, granted to B. M. Shipley, the present inventor, on October 12, 1926, A motor key 60 (Fig. 1) is provided to release the machine for operation. In order to release the machine a pawl 61 must be rocked from the-pathof a flattened stud 62 on an'arm 63 secured to the release shaft 42. A spring 64, (Figs 1 and 8) one end of which rests against a shoulder on a link 65, and the other end of which bears against a clip attached to an arm 66secured to the release shaft 42, con- V stantly tends to rotate the shaft 42 in a clockwise direction but is prevented from doing so bythe pawl'61. ".lhepawl 61 (Fig. 4) is disengaged from the Stud 0;. by the motor key Q 60, through a stud 67 (Fig. 1) engaging a lever ()8 pivoted on the sideirame 69. Upon depression of the motorkey '60 the lever 68 rocks an arm 70 (Fig. 4), yoked to an arm 71 which engages a stud on an arm 72. The

arm (2 1S yoked to a bifurcated arm 43 F g. 3), engaging a stud on the pawl 61. Therefore. rocking of the arm '1' O rocks the bifurcated arm 73 111 a clockwise direction to dis engage the pawl 61 from the stud 62, thus permitting the spring 64 (Figs. 1 and 8) to rock the release shaft 42 in a clockwise di rection to release the machine.

[fey release mecizanism.After the machine has been released, a main cam shaft 80 (Fig. 1) is given one complete rotation in the direction shown by the arrow in Fig. 1, by any suitable driving means, such as a motor clutch, as illustrated and described in the Letters Patent of the United States No. 1,619,796, issued to the present applicant on March 1,

' 1927'; said clutch being adapted to be connected with a motor such as shown and described in the patent to Charles F. Kettering and lVilliam Chryst, No. 1,144,418, issued on June 29,1915. Secured to the shaft 80 is a gear 81 meshing with a gear 82. The ratio of the gears 81 and 32 issuch that the gear 82 is'givcn a one half rotation for each full rotation of the gear 81. The gear 82 is provided with race having two cams 83, engaging said race is a roller 87 carried by a lerer 34. pivoted on the frame 69. Said lever also carries a stud 85 engaging a slide 86 (Figs. 1 and 8) supported on stud 88 on the link 65. on each full rotation of the shaft 80 and half rotation of the gear 82, one of the cams 83 rocks the lever 84 clockwise and then counter-clockwise. The clockwise movement of said lever 84, through the stud 85 and slide 86, lowers the link 65, thereby rocking the release shaft 42 in a counter-clockwise direction to normal position to restore the arm 63 (Fig. 3) ,and still farther past normal to cause the rod 40 (Fig. to engage the tails 39v to release the amount keys-as above de scribed. This movement of the release shaft 42 past its normal position also engages the arm 56 6) with the tail 55of the arm 54. thereby releasing the transaction keys.

Repeal? operaions.-Certain of the transaction keys 50 are adapted to control the slide 86 (Figs. land 8) in such a manner that when 1 the machine is operated the slide will be disengaged from the stud 85, and therefore the lever 84 will move idly until its stud 85 engages a shoulder 90 on the link 65, whereupon .the link will be lowered, but this time'only far enough to restore the arm 63 (Fig.3) to permit the release pawl 61 to again assume its normal position in frontof the stud 62. This movement of the shaft 42 is not far enough to rock the rod 40 and the arms 56 mean-e7 are not released; Any number of keys may be adapted to control this slide 86. However, in the present application, for purposes of illustration enly the six lower keys 50 are shown asa'dapted to control said slide 86. The three upper keys have no effectupon the slide 86and therefore when the machine is operated withany of these threekeys depressed the slide 86 remains in the normal position and therefore upon operation of the machinethe lever" 84, through its pin 85 and the slide86 lowers the link and rocks the shaft 12 and the amount and transaction keys are released.

Adjacent to the bank of transaction keys 50' (Fig.1 6) is a leverf91 having inclined edges 92 cooperating with the pins 52 0f the transaction keys for rocking the lever 91. This lever 91 (Fig. 6) has an integral arm '89carrying-a pin 100 engaging a'slot 101 in an arm102, connected by a yoke 98 to an arm 103. Thearm 102 is pivoted on a shaft 10 1 (Fig. 9) supported1by two of the usual differential hangers 111, and the arm 103 is pivoted one stud112'in the frame 69. The arm 10S earries a stud 9 1 adapted to engage an arm 95-01? a lever 96fpivoted on the link 65. The lever 96 is bifurcated to engage a projection 98 orrthe slide 86 and is adapted to hold theslide 86in the position shown by means of a spring 99. Depression of one of'the lower keys 50, by" means of the lever 91 and arm 89 reeks the'arms 102 and 103 counter clockwise and causes the stud 94'to engage the arm95 and roek the lever 96, thereby movingth'e slide*86towardthe left (Fig. 8), thus disengaging it fromthe stud 85. Upon subsequent operation of the machine the stud *will engageptheshoulder of the link 65', thereby restoring the releaseshaft to its home position, as above mentioned, but not far enough to release the amount and trans action keys. Release shaft owerthrow pram-eating means?- If the machine should be operated too rapidly,'it is possible to cause the release shaft 4-2 to be rotated past its normal orhome posi-f tion during the repeat operations, therebyaccidentally causing the amount and transaction keys to be released. In order to prevent this, the arm 66 (F igs; 1 and 8) is provided with a shoulder-105 into the path of which an arm 106 is rocked when any one of the lower transaction keys 50 is-depressed. The arm 106 tends torock into the path of the shoulder 105due to a spring 107," but is prevented from doing so by a stud 108 mounted on a bell crank 109.which is connected to the arm 106, and bya stud slide 86 away from the stud 108 on thejbell crank 109 and also move the stud 110'away from the bell crank 109. lVhen the slide 86 is moved toward the left upon depression of any of the lower transaction keys, as above described, the spring 107 Will tend to rock the arm 106 into the path of the shoulder 105 of the arm 66. However, the eel crank'109 is held against movement atthis time by the stud 110, but during the operation of the machine, when the link 65 is lowered, the bell crank 109 is permitted to move, thereby rooking the arm 106 into the path of the shoulder 105. he arm 106, therefore, provides a stop for the arm 66 when the arm 66 arrives at its normal position, in which position the pawl 61 is free to rock into the path of the flattened stud 62,thereby stopping the machine. Near the end of the upward movement of the link 65, the stud 110 engan'esthe arm 109, thereby O disengaging the arm'106 from the shoulder 105. 1

dllamml ice-y reZcase.After a series of, repeat operations have been made it is sometimes desirable to release the amount and.

transaction keys, for example, when it is desired to take a total or set up new amounts.

In order to permit this release of the .keys

Total taking0pe7'ati0as.-All of. the transaction keys 50 control the selection of'totalizers during adding operations. These keys also select totalizers during total taking oper ations for printing the totals thereon. However,-dnring total taking OPGl'tllllOl'lS, repeat operations are never necessary, and therefore the transaction keys'must be released during every total taking operation. For this reason it is necessaryto provide some means for preventing the arm 106 from moving into the patlrof tl'ieasheuider 105 of the arm 66 when one of the lower transaction keys is depressed for total taking operations, inasmuch as the key release shaft 4-2 is always -rocked far enough to release the depressed transaction keys during total taking operations.

i A total lever 125, (apart of which is shown inFig. 2), controls'the link 65 in'a manner whereby the stud 85 will engage a shoulder 126during total taking operations, thereby rocking the shaft 42 far enough to release the transaction keys. :lThis' 'n'iovemen't' of the lever 66 is'efl'ec'ted by means of a cam slot .127 (Fig. 2) which rocks an arm 128 which by-means of a spring 129 rocks an arm 130 in a counter-clockwise direction when the total lever is moved out of its addrposition.

arm 130is provided with a cam slot'131 whicn rocks an arm 132 secured'to a shaft Also lifts secured to the shaft 133 is an arm 134 (Fig. 1), which is adapted to rock an arm 135 by means of a link 136. The arm 135 operatesa pitman 137 connected to the link by means of a stud 138. From this it is apparent that when the total lever 125 is moved out of its adding position the lower end of the link 5 will be moved toward the left. This movement disengages the slide 86 from the stud and positions the shoulder 126 into the path of the stud 85. During total taking operations the gear 82 makes a complete rotation. Therefore the arm Set is given two oscillating movements during total taking operations. However, it is desired to maintain the transaction key depressed until near the end of the operation, and for this reason a cut-away portion 139 (Fig-s1and8) of the link 65 is moved into the path of the stud v85 during the operation of the machine. The pitman 137 has a roller 140 which is moved into a, cam slotl il when the total lever is moved out of its add position. This cam slot is so formed that during the first half of the rotation of the gear 82 the lower end of the link 65 is moved to the left far enough to position the cut away portion 139 into the path of the stud 85. Before the arm 84 receives its second oscillation, the cam 111 moves the link 65 back toward theright, and positions the shoulder 126 into the path of the stud 85. Then, upon second movement of the lever the stud 85 engages the shoulder 126, thereby restoring the release shaft 42 and moving it far enough past its home position to release the transaction keys. i

The pitman 137 has mounted thereon a stud 150 for preventing the arm 106 from moving into the path of theshoulder of the arm 66 during total taking operations. The bell crank 109 is provided with a forwardly extending arm 151 with which the stud 150 is adapted to engage when the total lever is moved out of its adding position. Upon depression of one of the lower-keys 50. afterthe total leverhasbeen moved out of its add position, the slide 86 will be moved toward the left, but the bell crank 109 cannot follow because the arm 151 engages the stud and therefore the arm 106 is prevented from moving into the path of the shoulder 105. Thus, during every total taking operation the release shaft will be freeto move far enough to release the transaction key.
